Drops of Tianmui (Complete Works Annotated by Liu Ji)

The numerology classics with Liu Ji's annotations as the core retain the original "theosophy" and "six-parent theory" framework, and incorporate Liu Ji's interpretation of the balance of the five elements and the view of destiny. The annotation is concise, focusing on the integration of Confucian "neutral" thought and Taoist view of heaven. Although the view is contrary to the later annotation by Ren Tieqiao, it established the theoretical system of "Dip Tiansui" and is an important version for understanding the perspective of numerology research in the Ming Dynasty.
